Who is going to pay for a non-cutting-edge fab that might be completely out of date relatively soon though?

Shouldn't countries wanting sovereign infrastructure create subsidies for creation of factories/job creation and also selling first/primarily within the region if it might cost on just a few million dollars (preferably a new competitor)

I think one flaw in my thinking could be that there might be a lack of experience within the people for something like this, do you consider it to be a factor and would it be difficult to hire people relevant to such fab?
